, .To cli-whom tt may conceive: l

Be it known that I, SAMUEL M. Bron, a cltizen of the United States,residingr at new and useful Improvements in Floor Pol ishing andFinishingl Machines, ol which the following is a specification.

My invention relates to a device for iinishing and polishing floors andhas 'for its object the provision or' a device of this charactercomprising means for abrading or polishing away from the surfaceabraded, any sawf dust or dirt which may be present upon thc floor andfor depositing theV dirt or saw-dust in a removable receptacle.

A further object of the invention is the provision of a deviceconstructed to accomplish the foregoing objects and having abradmg orpolishing members, and means for adjusting the pressure with which saidmcrnbers bear upon the floor.

Further objects and advantages of the invention will be slet forth inthe detailed description which now follows.

In the accompanying drawings: Figure 1 is a side elevation of a doorfinishing machine constructed in 'accordance with the invention, with a`ortion of the apron thereof broken away, big. 2, is a` plan view of thc'machine withl a portion of the apron broken away, Fig. 8 is atransverse vertical section upon the line of Fig. l, Fig. 44 is a detailplan' view of apair of reciprocatory cages herein# afterdescribedfandliig. 5 is a detail perspective view of e polishing blockhereinafter described.`

Like numerals designate corresponding parte in all of the ot thedrawings.

Referring to the drawings, the numeral 5 designates the side members ola tubular frame.. Vertically extending nieml'iers 6 are'secured to thesemembers by couplings 7, said members 6 being,r outturned-as at S andconnected by a cross bar *3 to form a handle. Brace bars 1l) connect themembers 5 and 6 by means of couplings 11. Casters i2 are carried by thecouplings 7 and serve to supportthe rear end o l' the frame. .A

14. l Cou lings 15 into which the forward ends of tne members 5 aresecured, are rigidly carried uion these vertical members The members 14are provided with casters 16 at their lower ond.

A framework 19` having ways 20 formed therein,`is secured to plates 21whichk are carried by the couplings 15, the connection between saidframework and said plates being compensating, such for instance as a.

`bolt and slot conncctionto permit of the movement of the 'frameworkwith relation thereto under circumstances of use which will behereinafter described. An apron 22 incloses this framework and liesbetween` the side members 19 ofthe frame and the plates' 2l. work,except that the apron forms a casing which is open at thebottom. Theapron 22. is provided with converging braces 17 which at their meetingends have collars A18 that surround the members 14 and ermit vof aslight vertical movement of said) its associated parts with relationthereto. Rcciprocatory cages 2d are slidably disposed This apronentirely incloses the trarne" apron and in the ways 20. These cagescarry depending blocks 25. Polishing blocks 26 are covered withsand-paper or other abrading material 27. A strip of felt 28 ispreferably-dis osed' between the sandaper and the bloc s to form ayielding cus iion. The blocks 26 are groovcd Aas at 29 and the ends ofthe sandpaper are carried beneath rods 30 which extend along thesegrooves. Latches 3'1 hold these rods in position and consequently clampthe sand paper in position. The blocks 26 carry castings 82 which areslotted 'as at 33 vfor thc reception olrpins 34 which are carried by thebloc 25. his pin and slot connection permits a limited vertical'movement of the blocks 26 with relation to the bloc-ks 25. Springs 35no1-mall tend to force the blocks 26-away from' the locks 25 and intoengagement with the oor.

A screw 36 having a hand wheel 37 mount ed upon the upper end thereof,is threaded' through the yoke 13 and has a swivel connection at 38 withthe top of the casing formed bythe framework 19 and the apron.

22. Condnits 39 and e() lead from this casing to a fan indicated at 4l.A second conduit 42 leads from this fan to a removable receptacle 43such as a bag, which is hung upon a hook 44. The fan 41 is driven by abelt e5 which leads from a pulley 46, said pulle in turn being drivenfrom a Vmotor 4T whic is su ported from a cross bar e8 by means of a`)racket 49. 4 controller 50 of the usual and well known constructioncontrols the speed of the motor and is mounted upon a controller board5l.
